The 1500 Megawatt Aperture Science Heavy Duty Super-Colliding Super Button (or simply the Super Button) is a button designed to be weighed down by certain materials within the facility. (for instance, the Weighted Storage Cube)

They were first introduced in Test Chamber 00 as a means of introduction to cube-and-button based testing. Once they have been weighed down, certain objects corresponding to the goal of a test will be activated. (opening a door, activating a High Energy Pellet, etc.)

Cube-and-button based testing was introduced in Aperture once the company had become financially unstable.
